ADuM3195 Datasheet Isolated Amplifier

Manufacturer: Analog Devices

Overview: Data Sheet ADuM3195/ADuM4195 Isolated Amplifier with Adjustable Gain and Single-Ended.

General Description

The ADuM3195/ADuM41951 are isolation amplifiers based on Analog Devices, Inc., iCoupler® technology.

The ADuM3195/ADuM4195 have very low offset and gain error, making them ideal for many isolated voltage sensing applications.

Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over lifetime and at high temperatures, the ADuM3195/ADuM4195 transfer functions do not change over lifetime, and are stable over a wide temperature range of −40°C to +125°C.

Key Features

  • High-Impedance input for isolated voltage measurement.
  • Low offset error and drift (output offset voltage): ±6 mV (Max) at 25°C and.
  • 22 µV/°C (Typ).
  • Low gain error and drift: ±0.5% (max) and ±27 ppm/°C (max).
  • Voltage-supply range.
  • VDD1: 4.5 V to 5.5 V.
  • VDD2: 4.5 V to 5.5 V.
  • Bandwidth: 210 kHz.
  • Isolation voltage.
  • 3000 V rms for ADuM3195.
  • 5000 V rms for ADuM4195.
  • Safety and regulatory approvals (pending).
  • UL recognition (pending).
